Hexamine (Hexamethylenetetramine) from Germany, India, and Saudi Arabia Injures U.S. Industry, Says USITC
The United States International Trade Commission (Commission or USITC) today determined that a U.S. industry is materially injured by reason of imports of hexamine from Germany, India, and Saudi Arabia that the U.S. Department of Commerce (Commerce) has determined are sold in the United States at less than fair value by Germany, India, and Saudi Arabia and subsidized by the government of India.
Chair Amy A. Karpel and Commissioner Jason E. Kearns made affirmative determinations of present material injury. Commissioner David S. Johanson made affirmative threat of material injury determinations.
Chair Amy A. Karpel and Commissioner Jason E. Kearns made negative critical circumstances findings with regard to imports of this product from India and Germany. Because Commissioner David S. Johanson made affirmative threat of material injury determinations, he did not reach critical circumstances findings for imports of this product from India or Germany.
As a result of the Commission’s affirmative determinations, Commerce will issue antidumping duty orders on imports of this product from Germany, India, and Saudi Arabia and a countervailing duty order on imports of this product from India.
The Commission’s public report on Hexamine (Hexamethylenetetramine) from Germany, India, and Saudi Arabia (Inv. Nos. 701-TA-738 and 731-TA-1713-1715 (Final), USITC Publication 5693, December 2025) will contain the views of the Commission and information developed during the investigations.
The report will be available by January 21, 2026; when available, it may be accessed on the USITC website.
Status of proceedings, links to relevant documents, and more information about the investigations can be found at the Commission’s Investigations Database System (IDS).
USITC Makes Determinations in Five-Year (Sunset) Reviews Concerning Quartz Surface Products from India and Turkey
The U.S. International Trade Commission (Commission or USITC) today determined that revocation of the existing antidumping and countervailing duty orders on quartz surface products from India and Turkey would be likely to lead to continuation or recurrence of material injury within a reasonably foreseeable time.
As a result of the Commission’s affirmative determinations, the existing orders on imports of these products from India and Turkey will remain in place.
Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns voted in the affirmative.
Today’s action comes under the five-year (sunset) review process required by the Uruguay Round Agreements Act. See the attached page for background on these five-year (sunset) reviews.
The Commission’s public report, Quartz Surface Products from India and Turkey (Inv. Nos. 701-TA-624-625 and 731-TA-1450-1451 (Review), USITC Publication 5691, December 2025), will contain the views of the Commission and information developed during the reviews.
The report will be available by January 13,2026; when available, it may be accessed on the USITC website.
BACKGROUND
The Uruguay Round Agreements Act requires the Department of Commerce to revoke an antidumping or countervailing duty order, or terminate a suspension agreement, after five years unless the Department of Commerce and the USITC determine that revoking the order or terminating the suspension agreement would be likely to lead to continuation or recurrence of dumping or subsidies (Commerce) and of material injury (USITC) within a reasonably foreseeable time.
The Commission’s institution notice in five-year reviews requests that interested parties file responses with the Commission concerning the likely effects of revoking the order under review as well as other information. Generally, within 95 days from institution, the Commission will determine whether the responses it has received reflect an adequate or inadequate level of interest in a full review. If responses to the USITC’s notice of institution are adequate, or if other circumstances warrant a full review, the Commission conducts a full review, which includes a public hearing and issuance of questionnaires.
The Commission generally does not hold a hearing or conduct further investigative activities in expedited reviews. Commissioners base their injury determination in expedited reviews on the facts available, including the Commission’s prior injury and review determinations, responses received to its notice of institution, data collected by staff in connection with the reviews, and information provided by the Department of Commerce.
The five-year (sunset) reviews concerning Quartz Surface Products from India and Turkey were instituted on May 1, 2025.
On August 4, 2025, the Commission determined to conduct expedited five-year reviews. Chair Amy A. Karpel and Commissioners David S. Johanson and Jason E. Kearns concluded that the domestic interested party group responses were adequate and the respondent interested party group responses were inadequate, and voted for expedited reviews.
A record of the Commission’s vote to conduct expedited reviews is available on the investigations page for Quartz Surface Products from India and Turkey; Inv. No. 701-TA-624-625 and 731-TA-1450-1451 (Review).
